Are there specific Toto toilet models that this tank is limited to. If it is model specific, how do I determine if my model is one of the applicable ones? I'm in Monterey County (California) and they have specific flush requirements for toilets any time home ownership changes hands. Our home is about to and all our Totos are 1.6 gal flush. We're looking into whether replacing the existing tanks with this tank will meet the requirements. We've been told that "might" be the case
Asked by: DonR9
Hi DonR9, This model Aquia tank is a dual-flush tank and can only be used on the dual-flush Aquia bowl (CT416). If your current TOTO toilet is a 1.6GPF, then you will not be able to use a dual-flush tank. Some newer TOTO toilets can be adapted from 1.6GPF to 1.28GPF, but some older ones cannot be adapted. You can determine this by finding the model number of your bowl. This is stamped under either side of the bowl where the tank is connected. Use a mirror or camera if it's a difficult spot to look. The model number will begin with a "C" or "CT" and followed by numbers and more letters. If the letters include an "E", then you can adapt the toilet to 1.28GPF by finding the corresponding tank. If the letters include an "S", then you will not be able to adapt it and you will need to replace the entire toilet in order to reduce the water consumption. If you have an "E", write down the model number so that you can determine the right tank. TOTO Technical Support can help you. They can be reached at 1-888-295-8134 between 8am - 8pm EST Mon-Fri and pressing "4" when prompted. I hope this helps and thank you for choosing TOTO!

How far apart are the mounting screws? I'm hoping I can attach this tank my existing bowl from another manufacturer.
Asked by: ImDoingARemodel
HI DoingARemodel, The TOTO Aquia tank is designed for use on the TOTO Aquia bowl only. This tank is not compatible with bowls from other manufacturers. Most modern toilets are engineered to only work with their counterparts and interchanging them could lead to issues with flush performance. If you like the look of the Aquia, we recommend you try the entire toilet. I hope this helps and thanks for considering TOTO!
